To model the cost, \( c \), of each bag of lemons, you can set up the equation based on the total cost and the number of bags. Julio bought 5 bags of lemons for a total of $19.75.
The equation can be written as follows:
\[ c \times 5 = 19.75 \]
To find the cost of each bag of lemons, solve for \( c \):
\[ c = \frac{19.75}{5} \]
So, the complete equation that models the cost of each bag of lemons is:
\[ c = \frac{19.75}{5} \]
